Method for producing porous device

摘要

A method for making a polymer with a porous layer from a solid piece of polymer is disclosed. In various embodiments, the method includes heating a surface of a solid piece of polymer to a processing temperature below a melting point of the polymer and holding the processing temperature while displacing a porogen layer through the surface of the polymer to create a matrix layer of the solid polymer body comprising the polymer and the porogen layer. In at least one embodiment, the method also includes removing at least a portion of the layer of porogen from the matrix layer to create a porous layer of the solid piece of polymer.

主权项

1. A method for forming a solid thermoplastic body with pores distributed through at least a portion of the solid thermoplastic body, the method comprising:
heating a surface region of a solid piece of thermoplastic to a processing temperature about one to twenty-nine degrees Celsius less than a melting point of the thermoplastic; holding the processing temperature below the melting point of the thermoplastic while displacing the surface region of the thermoplastic through a granular porogen layer to create a matrix region of the solid thermoplastic body comprising the thermoplastic and the granular porogen; and cooling the matrix region to cease displacement of the granular porogen through the thermoplastic.
